Members
| Value | Member | Description |
|---|---|---|
| 0 | V12 | Adobe Acrobat PDF version 1.2 |
| 1 | V14 | Adobe Acrobat PDF version 1.4 |
| 2 | PdfA | Adobe Acrobat PDF/A. PDF/A is a subset of the PDF standard that contains only those features that are suited for long-term archival. Primarily this means that the document will be completely self-contained: it includes all content, font and color information |
| 3 | V15 | Adobe Acrobat PDF version 1.5 |
| 4 | V16 | Adobe Acrobat PDF version 1.6 |
| 5 | V13 | Adobe Acrobat PDF version 1.3 |
| 6 | V17 | Adobe Acrobat PDF version 1.7 |
